Phoenix apartment fire temporarily displaces 40

About 40 residents were temporarily displaced Tuesday afternoon when an apartment fire left 18 units without power, according to the Phoenix Fire Department.

Fire Capt. Jonathan Jacobs said several 911 calls came in about 2 p.m. reporting smoke coming from a second-story window at an apartment complex near 23rd Avenue and Thomas Road.

Firefighters were able to enter the unit through the window and quickly extinguish the fire, Jacobs said. The power was turned off to the unit and 17 nearby units in order to find the source of the blaze, he said.

No injuries were reported and the investigation is ongoing.

Without electricity and air-conditioning, approximately 40 residents were put on a climate-controlled city bus to provide temporary relief, Jacobs said.

The temperature at Phoenix Sky Harbor International Airport was 105 degrees as of 3 p.m. Tuesday.

The National Weather Service issued a special weather statement Tuesday warning of high temperatures in Phoenix and most of southern Arizona.

"Strong high pressure over the desert southwest will bring the hottest daytime temperatures so far this year," the statement read, adding that high temperatures would top out between 103 and 108 degrees.

"Heat is a serious health threat and even the most seasoned residents may be affected," the statement said. "It is important to stay hydrated and limit outdoor activities to early in the morning or evening hours. Check on your neighbors who may be reluctant to use air conditioning this early in the season. Never leave children or pets inside a car for any amount of time."
